Current through Register Vol. 56, No. 24, December 18, 2024

Section 17:24-4.2 - Network design

(a) The following features shall be incorporated in the 9-1-1 enhanced network design and will, where appropriate, be provided for in any contract for such telephone services:

1. A four or more tandem switch architecture, featuring redundant, diversely routed links to all local central offices and between the tandems;

2. A network protection plan that permits network recovery from a catastrophic switch failure;

3. A mechanism to expeditiously provide switching and rerouting to a back-up 9-1-1 tandem in the event of a 9-1-1 tandem failure. The back-up 9-1-1 tandem shall provide selective routing, in a normal fashion, to the designed PSAP until the failed tandem has been restored;

4. A method to instantaneously default 9-1-1 calls to a PSAP or PSDP in accordance with the respective county 9-1-1 plan, in the event a 9-1-1 call cannot be routed to a 9-1-1 tandem;

5. Monitoring of all 9-1-1 tandems on a 24-hour, seven day basis by a 9-1-1 switching control center (SCC). The 9-1-1 SCC's responsibilities include the maintenance and repair of the 9-1-1 tandem switches. The 9-1-1 SCC acts as the central point of contact for all PSAP trouble reports via a toll free 800 number. The 9-1-1 SCC is also responsible for the expeditious repair of any other 9-1-1 network components affecting the critical 9-1-1 service; and

6. Monitoring of the Statewide 9-1-1 network providing 24-hour coverage, with priority 9-1-1 traffic flow from all dedicated lines, end offices, sector tandems, and operator services position system tandems into the 9-1-1 network.
